JAMES N. NUCKOLLS, OF SULPHUR ROCK, ARKANSAS.

BOLSTER-BLOCK.

To all whom it may concern:

Be itknown that I, J AMES l. NUoKoLLs, a citizen of the United States, residing at Sulphur Rock, in the county of Independence and State of Arkansas, have invented certain new and useful Improvements in Bolster-Blocks, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in bolster blocks, the primary object of the invention being to provide a bolster block with novel fastening means for detachably securing the block on to the end of the bolster.

Another object of the invention is to provide a bolster block which will possess advantages in points of efliciency and durability, is inexpensive to manufacture and at the same time is simple in construction and operation.

With the above and other objects in view, the invention consists in the novel features of construction and the combination and arrangement of parts hereinafter more fully described, pointed out in the claims and shown in the accompanying drawings in which,

Figure 1 is a side elevation of a bolster block constructed in accordance with my invention. Fig. 2 is an end elevation showing the lever in its unlocked position. Fig. 3 is a similar view showing the lever in its locked position.

Referring more particularly to the drawings, 1 indicates a bolster of any well known construction but preferably rectangular in cross section. Mounted upon each end of the bolster and detachably secured thereto is the bolster block 3. Secured to each side of the block are the bearing clips 4: in which are mounted the rock shafts 5, said shafts being arranged on a downwardly incline toward the outer end of the block. Formed integral with one end of the rock shafts and extending on an incline downwardly toward the inner end of the block are the arms 6 having their lower ends bent at right angles to form the inwardly extending portions 7 which are adapted to engage in the openings 8 formed in the bolster 1. Formed integral with the end of the shafts 5 are the upwardly extending arms 9 having their upper ends bent at right angles to form the outwardly extending portions 10. An operating lever 11 is provided having one of Specification of Letters Patent.

its ends enlarged to form the rectangular portion 12 which is provided with a central arranged opening whereby the lever is pivotally mounted upon the outer end of the block by means of the screw bolt 14. Formed in the enlarged portion 12 of the lever 11 and arranged at diametrically opposite points are the openings 15. Pivotally connecting the enlarged portion 12 of the lever with the outwardly extending portions 10 of the arms 9 are the hook members 16 hav-' ing their hook portions pivotally disposed within the openings 15. Formed integral with the outer end of the hook members 16 are the rings 17 which are loosely mounted upon the outwardly extending portions 10.

A collar 18 is mounted upon the rock shaft 5 and arranged at one end of the bearing clips 4 to prevent the longitudinal movement of the shaft in the bearing.

In securing my improved block to the bolster, the lever 11 is drawn to the position shown in Fig. 2, the block is then placed upon the end of the bolster and the lever 11 thrown to its operative position as shown in Fig. 8 so that the inwardly extending portions 7 formed at the lower ends of the arms 6 are disposed within the openings 8 formed in the bolster 1.

It will be seen from the position of the lever shown in Fig. 8 that the same is thrown downwardly far enough to substantially lock it in its operative position, so that it will not be accidentally unlocked to release the block from the bolster.

It will be understood that any suitable form of bolster block may be used, and the block may be either made of wood, iron or any other suitable material.

lVhileI have shown and described the preferred form of my invention, it will be obvious that various changes in the details of construction and.in the proportions may be resorted to for successfully carrying my invention into practice without sacrificing any of the novel features or departing from the scope thereof.

\Vhat I claim is 1. In a device of the character described, the combination of a wagon bolster having openings formed in each side thereof adjacent each end and arranged at diametrically opposite points, a bolster block 'mounted upon each end of said bolster, bearing clips arranged upon each side of the block, rock shafts mounted in said bearing clips, means formed integral with one of said rock shafts and adapted to be disposed within the open ings in the bolster, and means pivotally secured to the other end of said rock shafts and adapted to operate the same to remove or engage the first means with the openings in the bolster.

2. In a device of the character described, the combination of a wagon bolster having openings formed in each side thereof adjacent each end and arranged at diametrically opposite points, a block mounted upon each end of the bolster, bearing clips arranged upon each side of the block, rock shafts mounted in said bearings, clownwardly inclined arms formed integral with one end of said shafts, inwardly extending portions formed at the lower ends of said arms and adapted to be disposed within the openings in the bolster, and means pivotally secured to the other ends of said shafts and adapted to operate the same to remove or engage the inwardly extending portions with the openings in the bolster.

3. In a device of the character described, the combination of a wagon bolster having openings formed in each side thereof adjacent each end and arranged at diametrically opposite points, a block mounted upon each end, bearing clips arranged at each side of the block, rock shafts mounted in said bearings, downwardly inclined arms formed integral with one end of said shafts, inwardly extending portions formed at the lower ends of said arms and adapted to be disposed within the openings in the bolster, upwardly extending arms formed at the other ends of said shafts, an outwardly extending portion formed upon the upper ends of the second arms, an operating lever pivotally secured to the outer end of the block, means pivotally connecting said lever with the outwardly extending portions whereby the rock shaft is rotated to remove the inwardly extending portions from the openings in the bolster or engage the same therewith.
